# Visual circuit simulation on a Mac

I am currently trying to design a circuit on a Mac (some might say therein lies my problem). My goal is simply to design a rudimentary implementation of the circuit which I can visualise working I have tried:

• There is a library for CDxxxx ICs, search for it on the Yahoo LTspice Group, or on ltwiki.org. Otherwise, you can build those out of the basic elements found in the [Digital] folder (in the "place element" dialog). But, really, if you're after digital, then @Jules 's suggestion is better. – a concerned citizen Jul 12 '18 at 6:01
